Description

Right now, the constructor of the CsvTableSource can have up to 9 parameters. In Scala this might not be a problem because of default values, but Java doesn't have this functionality.

I propose to have a builder pattern here:

CsvTableSource
.builder()
.field("myfield", Types.STRING)
.field("myfield2", Types.INT)
.quoteCharacter(';')
.build()
